LONG-TERM SUCCESS OF SINUS AUGMENTATION USING VARIOUS SURGICAL APPROACHES AND GRAFTING MATERIALS

Two hundred twenty-two sinus augmentation procedures were performed us ing one of three techniques: crestal approach; lateral approach; or la teral approach with simultaneous implant placement. Forty-one of these sinus augmentation procedures were performed in conjunction with bucc olingual ridge augmentation. Of the 222 procedures, 217 (97.7%) were s uccessful. Of 510 implants placed in augmented sinus areas, 495 (97.0% ) were deemed successful by the criteria of Albrektsson et al for up t o 73 months in function. Clinical considerations in the execution of s uch therapy are discussed.
